'To all whom t may concern,.-

Be it known that I, CoLoMAN ROZR, a subject of the Emperor of lAustriaflungary, residing at 34 Maafeldstrasse, Nuremberg, Germany, have invented certain new and useful Improvements in Means for Casting Justifying-Spaces in Combined Type Casting and Setting Machines, of which the following is a specification.

The present invention. relates to type-set-A ting machines in Which'the type are cast in a given order and at the same time com posed into lines by aid of a perforated strip or socalled perforated register. This register represents the different characters and the spaces requisite for each line in the form of consecutive transverse rows of holes, the various combinations of perforations enabling the vari-ous characters, as Well as spaces of different thickness, to be cast. In constructing the perforated strip the hole combinations representing the spaces are selected and so arranged that the spaces cast in accordance therewith when inserted in the line bring it to the requisite uniform length-that is to say, j ustify the line.

To provide means for casting in a type easting and setting machine spaces according to a perforated strip of this kind is the object of the present invention.

In the accompanying drawings, Figure l is a plan view of a section of such a registerstrip as is employed in carrying out my invention. Fig. '2 is a diagrammatic View illustrating the various electrical circuits. 3 to 6 are details of part of theelectrical devices employed in carrying out my invention, Fig. 4 being a sectional View on the line B. B of Fig. 3 and Fig. 6 being a side elevation of the part shown in Fig. 5. Fig. 7 is an end elevation of the mechanical parts of my improved justifying` mechanism. Fig. 8 is a view taken on thelineiA Aef Fig. 7. Fig. 9 is an elevation illustrating part of the device shown in Fig. S. Fig.` 10 is a plan view illustrating features shown in Fig. 8, partly broken away. Figs. 11 to 20 are detail views.-

The perforated register for actuating the mechanism and which strip is illustrated in Fig. l consists of an endless hand of paper having a series of perfor-ations, the rows of perforations representingr the type characters losing indicated by the letters inscribed beregister is beingprepared the stripy movesv from right to left, so that perforations corresponding to those marked II I IV are formed at the end of the series of perforations repre* senting each line of matter.V When the types strip or' register moves from left toA right, as

indica-ted by the arrow, so that at the begin` ning of each new line the hole IV is the first.

to come into operation in order to'push to one side the line just composed and make room for the next line to be composed. After this the rows of holes I H properly adjust a stop for the core of the mold, so that/,the spaces Iwhich are cast whenthe holesIII `representing spaces come into operative position bring the lines to the prescribed length. By reference to Fig. l it will he seen that the perforations or holes in thesirip are' arranged in seven longitudinally-extending rows or zones, numbered, respectively', I 2 5 e 5 6 7. eration the register-strip passes between plate 8, Fig. 2, and seven contact-springs'l 3 i 5 6' 7', corresponding to the aforesaid zones of the strip, being advanced by suitable mechanism step by step, each interval being the same as the distance between the transverse rows of holes. At each adjustment of the register thosel contact-springs whose ends above the plate S are over perforations in the and spaces are being cast, the perforatedv In 'opstrip are brought into electrical connection IOO y., 6" 7" on a switch-lever12.

casting justifying-spaces which are represented on the register-strip by the transverse rows of perforations designated I II III IV.

My invention is particularly designed for use in connection with the type-casting machine described and illustrated in the aforesaidl Patent No. 628,631.

For the purpose of assisting in an understanding of my invention Figs. 1 and 2 herein illustrate a register-strip and an arrangement of electric circuits similar to those shown in said patent supplemented by the present invention. The latter only, however, is illustrated in the other views.

Referring now to Fig. 2, it will be seen that the contactsprings 1 to 7 are electrically connected by wires 9 with contact -plates 1X 2 3X 4X 5X 6X 7X, mounted on a plate 10 of insulating material. On said plate 10, are also arranged a series of contact-plates 1XX ZXX XX 5f XX TW, these latter beingl arranged in the same radial lines as contacts 1X to 7X and electrically connected by wires 11 with seven insulated contacts 1" 2 3 4" 5 A rotary shaft 13, passing through the center ol' the plate 10,

1- has an insulated arm 14, on which are carried contacts 16 17, that are electrically connected by means of a metal strip 15. As the shaft ld'rotatesin the direction of the arrow the -contacts 16 17 slide over the contact-plates referred to, the positive pole of said battery being connected with the plate 8 bya wire 21 and ihe negative pole connected with the contacts 1 to 7" of the switch-lever12,as required in a manner to be more particularly explained hereinafter. The shaft 13 is connected with the mechanism employed for advancing the perforated strip in such a manner that once during each revolution of the contact-s 16 17 and during the time they are passing over the strips 1S 19 said register or perforated strip is advanced a distance equal to that separating the transverse rows ot' holes, and the said register-strip then rests or remains stationary with one row of holes under the free ends ofthe contact-springs 1 to 7, while the contacts 16 17 pass over the plates 7 7XX to 5 XX. ing the combination of holes representing the Aletter M on the registerstrip, (illustrated in Fig. 1,) which consists of four holes in the zones 7 l 2 4, is under the contact-springs four circuits are successively closed during one revolution of the shaft 13 as the sliding contac-ts 1G 17 pass over the plates 7 7), 1X 1m,

Forinstance, when the row contain- 2X 2XX, 4X cxx, and tir-.ese four circuits actuate suitable devices` 'like those and in the manner described i' the aforesaid United StatesLettersPatento.628,631,forexample) by which during the remainder of the revolover these plates. By suitable means controlled by the closing otsaid circuit and not forming part of the present invention the completed line of type is moved aside in order to make room for the next. At the same time a suitable mechanism is connected with the shaft 13 during three succeeding revolutions thereof, which by three distinct movements adjusts the lever 12 from the position illustrated,first,over the tripartite contact 23; secondly, over the tripartite contact 24, and, thirdly, back again intoits 'original position. Ae the perforated strip is advanced three steps during these three revolutions of the shaft 13--that is, simultaneously with the three adjustments of lever 12the position of the lever 12 over the contacts 23 or 24 will coincide, respectively, with the positioning of the transverse rows of holes I and II under the contact-springs 1 to 7', and when the row of holes in the register nentA following that one marked II (which row represents a letter) comes into operation lever 12 again assumes its normal position (shown in the drawings) and enables the first letter of the new line to be cast.

In the preceding paragraphs I have outlined brieily the method ofoperation of such a machine as is illustrated and described in the United States Letters Patent No. 628,631 with my invention applied thereto. As the castingof type, however, formsno part of my present invention, I will. only describe in detail the method of and mechanism for casting justifying-spaces, which mechanism is controlled by the rows of holes in the regis- `ter-strip marked I and II and by the movements of the switch-lever 12 over the contacts 23 24.

The principle of justifying followed in carrying out the presentinvention consistsin providing types and spaces which are graduated in thickness and' vary from each other by relatively small units and in assuming that the words in a line are separated by spaces of medium thickness, the remainder or excess space then being distributed uniformly as far as possible among all the spaces and the undistributed remainder, if any, (which must necessarily contain a less numberl of units than there are spaces,) allotted by singlev units to as many of the IOS) IIO

spaces als, is necessary; For example, I will .assume that each of the ordinary or medium spaces has a thickness of ten units and that a line containing eight of such spaces lis found to be forty-three units too short. To justify such a line by following the principle above stated, it is necessary to either increase the "thickness of each of thespaces in the line by live units and to further increase "threel of the spaces to the amount of one unit-that is, three ofthe spacesy must be made of the thickness of sixteen units each 'and yfive of the spaces given a thickness of y -tifteen units each-or each of the eight spaces must be increased in'thickness by six units land'to equalize this five' of the' spaces re- .duced in thickness by onennit each, (thus providing three spaces of sixteen units each and ivespaces of fifteen units each.) If

under the conditions assumed the provi sional line is too long by forty-three units,

then it is necessary to 4either reduce the tions in the rows III of the register are arranged .in such manner as to carry out the principle of justifying above referred to. The perforations or holes in row Il indicate the number of units by which each of the spaces in the line represented by they rows of perforations between said row llA and the next co1iespondin, row of the register must vary in thickness from the normal or medinm spaces-that is, a hole in zone l2 3 4 5 of row II indicates a variation in thickness from the normal space of one, two, three, four, or five units, respectively. As usual, the ,variation required is greater than live units. y Said row Il generally contains aseries of perforations, the required variation being equal to the suxn of the numerals designating the zones in which the holes are situated. In Fig.y l, for instance, there are three holes in row II-one each in the zones 2, 3, and 4. This combination of holes consequently represents a variation from the normal equal to the sum of said zone-nu merals 2, 3, 4, or nine units, and indicates thateach spacing-piece of the succeeding;r line must vary to theextent of nine units from a normal space. The row of holes marked I never contains but one hole on any of the zone-lines l to 5, and this hole indicates, according as it is situated in the zones l, 2, 3, 4, or 5, the number of spaces among which the remainder or excess of variation required to justify a line must be distributed by single units after the equal distribution of Variation to all of the spaces as represented in row Ii. This remainder can never amount to more than five units, because in perforat-ing the register-strip the remainder or excess, even in lines of more than ten space-places, is still onlydivided into ten spaces, the other s aceplaces being illed by'spaces of normal t ickness. The distribution of spaces according to the principle set, forth above permits of having a remainder the total number of units in whichis less than half the number 'of spaces. Whether-the variations indicated by the rows I II are to be added to or sub tracted from the normal space is indicated by holes i-n the zones 6 7, a hole in one of said zones always appearing in each of said rowsthat is, a hole in zone 7 indicates addition, while a hole in'zone 6 indicates subtraction. This is clearly shown in Fig. 1, where the sign of addition is placed above row II and the sign of subtraction aboverow I. Therefore according to the example illustrated in Fig. 1 the two rows of holes II and l indicate that eachof the spaces in the line represented by the rows yof perfor-ations between said rows I II and the next succeeding similar rows on the register must 'be nine units thicker than the normal space, and three of such spaces must then be reduced by one unit each-that is, of the spaces necessary for justifying this line three are to be made eight units thicker and the others nine units thicker than the normal space. The essential problem of `the invention is therefore to regulate the core of the mold which becomes 0perative when the spaces are being cast, so that the spaces prescribed by the rows of holes I II are correctly formed. This is effected by adjusting the core as required by the means controlled by the rows I and II, so that the spaces which varyfroxn the normal space by one unit each'will be cast as the rows III successively comeinto operative position until the requisite number' of such spaces is cast, and then the core is automatically adjusted into another position, so that for the rest of the line only spaces of the thickness prescribed by the row of holes 1I are cast.

The particular means illustrated in the accompanying drawings as Aan embodiment'of my invention will now be described.

Referring first to Fig. 2, it will be seen that the divisions 25 26 of the tripartite contact 23 are electrically connected, by means of con doctors 25 26', with the windings of a pair of electromagnets 25/J 2,6. Said magnets are connected with a conductor 29 by wires 27 28, and said conductor 20 is connected with the return-wire 22 of the battery. Similarly the divisions 30 3l of the tripartite contact 24. are v electrically connected by wires 30'31.' with the windings of a pair of electromagnets 30 3l", said windings being also connected to the return-wire 22 through wires 32 33 and the conductor 29. Above each of said mabnets is arranged a con tact-screw, it being cairried by an angle-plate that is insulated from ICO IIO

the magnet. Between said contact-screwsi vibrate armature-levers' 34 35, which are4 sulated at their pivotal supports and are connected with spiral springs 36 37. On a conducting-pillar 38, arranged centrally between the pairs of electromagnets 25" 26" and 30" 31", is pivoted a connecting device having three arms 39 4041. The arm 41 extends intothe field ofthe electromagnets 25" 26" and is attracted by that one of the electromagnets of said vpair which is energized, and thereby moves the arm 39 or 40 into contact with the upper angle-piece of the nonexcited electro magnet. The said arm 4l has a springfork 47, with which the armature-lever 34 engages. The upper insulated angle-pieces of the electromagnets 25" 2G" 30" 31" are electrically connected by wires 25) 26 30) 3l with the windings of four electromagnets 25) 26) 30) 31), which magnets are also connected by Wires 42 43 44 45 to a bar 4G, to which the return-wire 22 is attached. The operation of the electrical devices last described, which is controlled by the rows of holes l Il of the perforated register, is as follows: If the row of holes I is in operative position under the points of the contact-springs 1' to 7' and the switch -lever 12 is moved lo the tripartite contact 23, then as the sliding contacts 1G 17 pass over the plates 6X (5XX a circuit is closed from the positive pole of the battery through the contact-spring 6', (which contacrswith plate 8 through the hole in zone G of row l of the register,) the corresponding wire 9, the parts 6) 17 15 1G 6), the corresponding wire 11, contact o", contact 26, wire 2G', electromagnet 26", and the wires 28, 29, and 22 to the negativepole of` the battery. The electromagnet 26", which is energized by said current, attracts the armature-lever 34 and the arm 41, so that the lever comes into contact with the screw in the upper angle-piece of said electromagnet and the arm 39 oontacts with the upper angle-piece of the electromagnet 25". 'lhe levers 34 and 39 are held in their adjusted positions by the spring 36 and b y the engagement of the fork 47 ofthe arm 4l with the lever 34. Then during the same revolution of the shaft 13 as the sliding contacts 16 17 pass over the lplates 3) 3), the row of perforations l of the register being still under the points of the contact-springs 1' to 7', and the switch-lever l2 over the tripartite contact 23, a circuit is closed 'from the positive pole of the battery to the plate 8, the contact-spring 3', (which rests against said plate through the perforation in Zone 3 of row L) thecorrespouding wire 9, the parts 3) 17 l5 16 3), the corresponding Wire 1l, contact 3", the plate 4S of the tripartite contact 23, the wire 49, connected therewith, the armature-lever 34, the upper angle of the-electromagnet 215", wire 26X, the winding of the electromagnet 26),and the conductors 43, 4G, and 22 to the negative pole of the battery. The electroniagnet 20) is consequently energized and its armature 50, Figs. 7 and 8,

attracted. By the movement of this armature a disk 51 (as explained later in thedescription of the mechanical part of the invention) is shifted the distance of three teeth, owing to the tircumstance that the hole of row I now operative is in the zone 3 of the register. It' instead of being in the register zone 3, the hole in row through which the second circuit is closed, were in the zone 1 2 4 5 the aforesaid disk instead ot being moved a distance of three teeth would ce moved one, two, four, or Five steps, re'sijiectively. it the hole in row I through which the first of said circuits is closed was ih the zone 7 of the register then, as is evident from Fig, 2, said first circuit would become closed as the sliding contacts 1G 17 passed over the piates 7' 7), through the contacts 7" 25, wire 25', the electrmnagnet 25", and the conductors 27 2S) 22. The positions of lever 34 and arms 40 4l would thereby be the reverse of those previously described, and accordingly the second circuit would include the conductor and the electrouiagnet 25m. The armature 52 of magnet 26) operates a disk 53, Figs. 7

and 8, and this disk would thus be moved a in the zone 7 of the register) through a Wire 11, the contacts 7" 30, the conductor 30', the

electromagnet 30", and the conductors 32 29 22 to the negative pole of the battery. The energizing of the electromaghet 30 moves the armature-lever 35 into contact with the upper angle-piece of' said magnet. During the remainder of the revolution of the shaft 13, while the row of holes 1I is still under the contact-springs 1' to 7' and the lever 12 is on the tripartite contact 24, the sliding contacts 1G 17 pass over the contacts on the plate 10 and successively close (according to the hole combination illustrated in Fig. l) three circuits, including the contacts 2 2) 3 3) 4X 4), the contacts :2" 3" 4, the part 54 of the tripartite contact 24, the wire 55, the armature-lever 35, connected therewith, the upper angle of the electromagnet 30", wire 30X,

included a perforation inthe sone-6 instead rimes of one in zone 7, as illustrated in Fig. 1 and. assumed in theprecedingdescription, the first a 3l, wireBIX, electromagnet 31), and conductor 45, and the armature 57 of magnet SIXX would actuate a disk 59.'

'From the explanation already given it is obvious that in cases where the entire spac ing of a line permits of its being distributed equally to all the space-places without any remainder the register will not contain any row of holes like that designated I, and there-- fore when this unperforated section of the strip passes lunder the contact-springs l' to 7' neitherofthe electromagnets 25XX 26XX will be energized. Similarly, in cases where the line can be spaced outvexacLtly with spaces of medium normal thickness the register will not contain any row of holes corresponding' to that marked II herein, and consequently when that section passes under the contact springs lf vto 7' neither of the'electromagnets 0 31XX will be excited.v In these two cases the disks 53 5l or 58 59 will consequently not be moved out of their normal position. As previouslystated, spaces (the thickness of which is determined previous to beginning to cast the type to form the line by the action of the rows I Il) are cast as the rows III successively come into operative position.

As hereinbefore stated when explaining the principle ofjustifying according to which Y the present invention operates and as will be obvious, it is generally necessary to employ in a line two sizes of spaces, there being about one unit of dilerence in thickness between the two sizes. Means forinsuringthat when the desired numberof spaces of one size has been cast the mold-core will be automatically adjusted so that thereafter spaces of a differont size will be cast are also-controlled hy the rows of perforations III in theregister. For thispurpose when the hole in row III comes under the contapia-sprint,r 3', the circuit thereby closed, the switch-lever l2 being in the position illustrated in Fig; 2 causes an insulated contact-piece'to pass between contact-springs 60 6l, Fig. 2. The conductoi' 62, connected .with contact 60, leadsto 'the positive pole oli'` thc-battery, while lthe other conductor 63, which is connected to contact til, is in electrical connection with a contact-cylinder 64. -A second'contactcylinder 65, operating alternately with 6ft is connected by means of a wire 6,6 with the aforesaid pillar-conductor 38, This conductor 3S has an electrical connection with the arms 39 40 4l,and therefore alsorby meansot the upper angle of `that electromagnet 25" or 26, against which the lever-arm 39 or 40 rests, is electrically connected'with the windings otthe corresponding'electromagnet 25Xl` or 26 and through said magnet with the wire 22,

leading-to the negative pole of the battery It follows, therefore, that if the two contactcylinders 64 65 come into electrical contact by means of the aforesaid contact-piece com nesting thecontact-springs l61 a circuit on the path given above isclosed and` according to the position of the arms 3940 41. the electroxnagnet 25XX or 26XX is energized, so

that in one case the disk- 53 and'in the otherV case the disk 5l is advanced ouetooth.- In

this respect it is to be statedas follows, having regard te the previous explanations: If at the beginning of *the line the-electromagnet 25XX was excited by the row of holes I and the disk 5 3 consequently moved,then as' the arm 40 cornes in contact with the upperv angle of the electromagnet 26" the electromagnet 26x would be excited 'bymeans of vowing to the lever-arm 29 touching the upper 'angle of the electromagnet 25, the electromagnet 25XX'wonld he excited by means of the row of holes lIII ofthe same line and the 'disk 53 moved on one tooth. The contactcylinders 64 65 are soarranged that, asshown in Fig. 5, whenA in their normal position they are not in electrical connection; but they come intoelectrcal connection when the one is displaced with relation to the other. The

two cylinders are mounted in a frame 67 and are adjustable longitudinally by pulling on arm 68, that project from rods connected to the cylinders. Cylinder 64 consists bf two insulated metal casings 69 70,wh ich are sepsrated by a vulcanized-rubber ring 7l and electrically connected with each other by a metalspring'72. Cylinder 65 also consists of two insulated metal casings- 73 74, with a metal ring 75 between them", which ring is capable of a slightmovement laterallyof the cylinder and is held against cylinder 64 by a spring 76, said spring forming'v at the same time a metallic connection between the casing`73 and the ring 75, while the electrical connection of `the ring 75 with the casing 74 is insured by reason of the ring restingon the upper edge of-this casing. In the normal position of the cylinders 64 65, as shown in the drawings, the metal ring 75 is in contact with the rubber ring 7l, and the circuitthroughsaid cylinders and theconductors 63 66 is open.. If,

however,the cylinders are adj usted so that the ring 75 contacts with either casing 69 70, said conductors 63 66 are electrically connected, which connection lasts until byinoving one 'of the cylinders the latter are'brought into the relative position illustrated inFig. 5, in which the rings 71 75 are in contact. The arm 68 of cylinder (35 is connected by a cord 77 with the periphery of disk 53, and the correspon'ding arm ot cylinder 64 is connected by a cord with the periphery of disk 5i, so that when these disks are moved the said cords are IIO wound thereon and the cylinders are raised correspondingly from their normal positions.

By the action of the row of holes I one of the cylinders 64.- 65 is adjusted so that the cylinders come Iinto electrical contact. Consequently each time .a row of holes III comes into operative position the last-mentioned ci rwill be repeated until the other cylinder, which 'is thereby lifted step by step, is raised as high as the cylinder previously lifted bythe action of the row of holes I. Having regard to the previous explanalions and taking as a basis the row of holes I illustrated in Fig. 1, the whole operationwill be as follows: By the action of the row of holes I the-electromagnet ZGXX is excited, the disk 5l, attached thereto moved around three teeth, and its cylinder 64 raised a corresponding amount. -The first row III of the perforated register following to the left then excites tho electromagnet 525XX and moves its disk 53 around one tooth and raises the cylinder 65 one step, the said cylinder, however, not yet being as high as the cylinder 64, so that both are stil-l in electrical contact and the next row of holes III can again excite the electromagnet 255x. Consequently by means of the said row III disk 53 is again moved on one tooth and cylinder 65 raised a corresponding-amount without yet rising'to-the same height as cylinder Ut. The third row of holes III can therefore still excite the magnet 25X and make the disk 5I advance 'a third tooth. By this movement the cylinder 65 is once more raised one step and now reaches the selne height as the cyl-v in der 64, (which was raised at one movement three teeth when row I was in operative po sition,) so the* the rings '.75 and 7l come into contactand th electrical connection between the two cylinders is broken. Consequently although each following row III of the lino will adj ust the contact-'piece between the contact-springs 60 61 the circuit through the conductors 63 66 will not he closed and there will be no adjustmentof cylinder 65. Finally when the hole lV cornes into operative position both the cylinders 64': and 65 return to their original position, as shown in Fig. 5, and the disks 51 53 are returned into their first position by means of springs, so that at the beginning* of a newline the cylinders and the disks are again in their normal position.

The mechanical part of the invention now about to be described is designed to transform the impulses ot' the electromagnets 25XX 26XX and 31XX, according to the signification of'rows I, III, and II, into movement of the aforementioned disks and by means of these movements to adjust a piece 78, Figs. 7 and 8, which determines the thicknesspf the spaces to be castand forms a stop for the core of the mold belonging thereto; also, to cause said stop to operate at the proper time, and, finally, at the end of a line to return the disks 53 51 58 59 and the cylinders 64 65 to their normal position.

rlhe disks 51 53 (illustrated in section in Fig. 1G) are provided on the edges of their adjacent faces with projections and recesses, as shown more particularly in Fig. 17. The projections of the disk 51 are double-stepped, and the lower steps 79 only extend sufficiently far so that when the disk 5l (see inner View, Fig. 15) is moved in the direction of the arrow a distance controlled by a single tooth S0 the steps 79 release the teeth 8l of the disk 53, so that the two disks can then lie-moved closer to each other a distance equal to the width ot" spaces 82 83, which corresponds to a decrease of one unit in relation to the spaces in the common thickness of the two disks.

other hand, disk 53, which, like disk 51, is f provided on the edge with teeth, is moved in the direction of the arrow-that is,in the saine direction as disk `5l--its steps 8l will come in front o the steps 86 of the disk 51, so that both disks are moved apart out of the position illustrated in Fig. 17 the amount of the double gap 82 or S3, which isequal to an increase of one unit in relation to the spaces in the common thickness of the two disks. At the same time it will be seen from the above, with reference to Fig. 17, that if one of the disks is moved a. certain number oi teeth (one to five) and the other disk afterward moved the same number of teeth both disks wili thereupon assume the position with regard to each other illustrated in Fig. 17.

he disks 58 59 have at the edges of their adjacent faces two cam-surfaces 87 88 and 89 90 or S7' 88' and 89 90', respectively, which ascend from 87 to 88 and from 89 to 90 and from 88 to 87' and from 90' to 89', respectively. The disks 58 59, which in Figs. 19 and 2l are represented as separated to a oonsiderahle extent for the sake di clear illustration, in reality touch eachother with their cam-surfaces, and their normal position with regard to each other is that vshown in Figs. 1S and 20, in which the central line a: y is covered by the line :t y'. IE the disk '58 is moved in the direction of the arrow, Fig. 18, from this normal position, the carmsurfaees of both disks move apart, which results in an increase in thecommon thickness of the two disks by as many units as the number of teeth 91 which the disk 58 is advanced. If, on the other hand, disk 59 is moved from its normal position in the direction of the arrow, Fig. 20-t'. e., in the same direction as disk 58 around a given number of its teeth 91', a corresponding gap will arise between the eamsnrfaces ot' the two disks, so that they can he adj usted close to each other, which is equal to decreasing the common thickness of the rtg teeth 91 moved. "Thedisks 5153 58 59 revolve.

ons. pivot 92, which is located in the frame 93 ofthe machine and has one fiat-tened end 951, securely iixed in a block A95 to prevent its turning. The pivot 92 extendsthrough a sleeve 96, revolubly' mounted in the frame 93,which sleeve' carries a fixed disk 97. This latter bears, Fig. 8, on vtheleft side against the frame of the machine and serves as a support at the left side for all of the disks when the outer-.disk 59 is pressed to the left.. The pivot 92 bears a iixcd tie-disk 98, and between this and a 'second disk 99, xed on said pivot, is revolubly mounted a disk'78, Figs. 7 and 8. With this latter disk engages a double lever 101 102, which is pivoted at 100, Fig. 7, so that when this lever is rocked by a p in 103 the disk 78 is adjusted into the position illustrated in Fig. 12 and its projectingpiece 10-1 comes into the path of an adjustable stopi screw 106, which is fixed on the core-carried i 105 of the mold, 1712.8. In this manner the core-carrier,ad vancinr under spring-pressure toward the disk 78 receives a variable stop, the adj nstment of which varies according to the extentofdisplacement of thedisks l 53 and 5S 59 from their normal positions. The pressnreoi the screw 106 is transmitter] by means of the tie-disk J8 to the disks 59 58 53 5197 and finally absorbed by the frame ofthe machine.

, As the pivot 92 is adjustable"longitudinally,

'if thelnnited thickness of Athe disks 51 53 58 for casting spaces ofnnedium normal thick-Y ness. 11", on the other hand, the disks have been moved out of their normal position, the core-carrier 105 is correspondingly adjusted and thicker or thinner spaces are cast, varying from the normal space hy a-nuinber of units corresponding to the adjustment. 'lhe pin 103 is only actuated for rocking the lever 101 102 and the disk 78 when a spacing-hole Ill comes under the contact-spriur 1 to 7', so that although an adjustment ot' the disk 73 in the direction ofl the length ,of pivot 92 is eii'ected as the rows of holes I Il become operative through movement of the disks 51 53 5S 59, said disk 78 only connes into operationwhen 'the spaces are east. In casting type (between the spaces) lever 101 102 occupies the position indicated in hig.7,the disk 78 being ont of the path of the striking-screw 106 of the core-carrier, which is capable of being adjusted by other means, not forming part of vthe present invention, to the thick- Jfr ness of the type to be cast. (See United States l `Letters Patent No. 628,631.)

` vThe rotation of the disks 51 53v 58 tn an extent equal to the' number of teeth 'corra spending to the hole combinations 1 I1 isefv I fected by the following means, (see Figs. 7, 8, On a continuouslyfrevolvingshaft 109, which is synchronized with the shaft 13,'Fig- 2, is secu red aca-m 110, having sii peripheral steps 1111,12 113 114 11.5 116. `The steps 111 and 116 project an equal distance beyond the periphery 117 o1'I the disk, while the steps 112',

113, 114, and project two, three, four, and tive times as far beyond said periphery. A roller 121, carried by a doublet-lever 119 120, fulcrtnned on a' pivot 118, is kept constantly against the edge of the cam 110 by means of a spring 122, so that said lever is continuously,

rocked as the steps 111t'o 116 pass said roller.'

AThe forked free end of lever-arm 120 engages a pin 123 on disk 97, whichdisk has a vprojecting edge 124, that is connected with aseg- Y ment 12e, Figs. rand i0, by means' of all erm `125, Figs. 10 and 11,.said arm extending past the disks 51 53 58 59. A spindle 127 has its ends jonrnaled in the segment 126 vand the edge 121 of the disk 97, and on said spindle are nxed a series, ef projections y12s 1.29 13o:

131 132. 'lheprojection 128 is arranged close to the segment/1:16, while the other projections are adapted/'to engage pins 133 on pawls 131 135 136 l/l/loosely mounted on the spindle 127. The projections 129 to 132 and pawls 135c to 137 are so distributed on the spindle that the pawls lie in the planes of the toothed rims ofthe disks 51 53 58 59, so as to be able to engage with the teeth of said toothed rims.

The teeth of the pawls are so wide that even i ,if the disks 53 58 59 are moved laterally the toothed rim thereof will remain in engage'- ment wint the pawn. The pawn 131 to 137L lare caused to engage with said toothed rims by means of leaf-springs, arranged between said pawls, and a pin or rod 138, extending between segment 126 and the disk edge 124, but are normally held out of engagement by means of catches 139 140 141 142. These catches are pivoted on a pin or rod 143 .and

by meansof springs arranged between their` lower arms and the rod 138 are pressed to- XIDY ward the pawls, the free upper ends of the catches engaging over the knife-edged ends of thepawls. 1n the normal position of the lever 119 120, which controls the movement' of this system of parwls, (illustrated in Fig.' 7,)

the projection 1 28 is, by the pressure of spring 122,pressed against'a stop A1-18 on theV machineframe, and the parvis 134 to 137 are prevented by the projections 129 132 from-engaging with the toothed rim, even if the catches 139 struction to movement of .the pawls 134c to 137 toward the justifying-disks, and therefore those pawls which are' released by their catches 139 to 142 infrage with their respective toothed rims and niove the disks enraged according1 to the stroke given by the lever 119 120. The several parte are of-such size and so related that by accurately retinlatinyf, an adjustable, stop 148 the disks 5l 53 58 59 will be shifted two, three, four, or' live teeth, respectively, by means ofthe steps 111,112,113, 114, or 115. The step116,which corresponds with 111, likewise effectsa -inovement of one tooth. The catches 139 to 142 are released by energizing the electromagnets 26XX 25 30Xx 31XX. The armatures 50 52 56 57 of these magnetsare nach, connected to one Iarm of a two-armed lever 149, which lever is pivoted on the frame of the machine and connected with said armatures by rods 150. The

other arms of said levers act on the lower arms of the catches and are adapted to adjust them into the position illustrated in Fig. .11.

i The notches 151 in the lower arms of the are moved around as many teeth as is indi# cated in units in the zones 1 to 5 of these rows, the disks and 58 being moved if those rows contain a hole in the zone 7, and the disks 51 and 59 if the rows contain a holejn 'the zone 6. Lu accordance therewith. the disk 781s so adjusted thatv spaces are tastA which tnicker or thinner than the .normal mediumsized space by the necessary number of nuits.

It is evident that the steps of the continuhusly-revolving (even when the machine casting letter-types) cam 110 effect the rocking of the lever 119 120 and the system of pawls, but do not move the disks 5l 53 5S 5i) unless the electronn 250 S36) 30XX 31 are ene ized at the same time. Likewise, also, step 116 does not effect any movene t ii, s one ot' c olectrornagnets 25 'e rewhen, l`eee cornes time step riz-ves that (as will be recollected) the contact-c 'vll inders 64 65, Figs. 5, 6, are in electrical. cohtact with each other. Then when the sie 116 passes on disk 51 or 53 is moved a distance of one tooth, according as the circuit is i closed over .the'electromagnet 25 or 26 The disks 5l 53 58 59 are fastened to spiral springs 155 by means of cords 153, Fig. 7' which are secured in peripheral grooves in the disks, Figs. 16, 2l, said springs being xed at one end to the frame of the machins The disks are kept in their normal position by means of these springs and after the movement taking place at the end,of thefhine are returned thereby to such normal position, in which they are supported by means of a step 156, contacting With'a lug 157 on the machine-frame. The cords of disks 51 53 are also connected with the arms 68 of the oontact-cylinders 64 65, as shown by the line 77. In the normal position of the disks 51 53 t-ihe cylinders 64: 65 are also in their norm'alposition, (see Fig. 5,) in which they are lnotin electrical contact. As previously expiained, when a row I comes into operative position one ofthe disks 51 53 is moved a certain .nu inber of teeth -and its respective cylinder is correspondingly raised. Then as the several rows III come into operative position the other of said disks is successively moved on` one tooth and the other contact-cylinder is correspondingly raised until both disks and cylinders resume their normal positions with regard to each other, Figs. 17 and 5. This latter movement of one tooth at a time is ei'feeted by means of the step 116 of the cam 1). As the disks 51 53', (ses the previous explanations with' reference to Figs. 15, 16, and 17,) now in their normalposition with regard I to each other, represent an in terrnediate piece'which is thicker or thinner by a given amount than their common thickness after they have each been displaced from their normal position, it follows that as soon as they have returned to their normal position the disk78 will be displaced before the casting of the next space. The steps ofthe disks are arranged so that this displacement amounts to one units-space. Therefore after the disks 51 have assumed their mutual normal position the casting of the spaces of oney sort ceases and the casting of the second sort of spaces diiering by the thickness ofcne unit from the first sort begins, as has been previously explained.

In order to se fes Pri

Ico

cure the disks 5l 53 58 59 in their position after each movement against the pull of the spring 155, a lever 158 is pivoted to the frame st 100, Fig. 7. A spring 159 acts againsta horizontal arm 160, provided with a series of spring-catches. 161, in such a manner as to cause said catches to engage the toothed rims the disks. When the hole IV of a iine comes into operative position, a pin 162 is actnated,^which pin presses against the lower arm of the lever S, thereby turning the lever into the position shown in Fig. 13, and thus raising the catches 161 out ofthe toothed rims of the disks, which latter are then, byv

are to receive spaces of normal thickness,

while for the correct adjustment of the disk 78 for casting these normal spaces the disks 51 53 58 56 must resume their normal position, it therefore results that in lines with more than ten space-places the disks-51 53 5S 59 must be restored to their normal position before the eleventh space has been cast, so that the eleventh and following spaces are cast in the normal position of these disks. For this purpose lever 101 102,- Figs. 7, 12,13, 14, carries on its axle 100, which is journaled inthe piece 163 of theA machine-frame, a lever 164, having a spring-actuated pawl 165,

which engages a ratchet-disk 166, loosely4 mounted on the axle 100, and movesthe said disk around one 'tooth every time the lever 101 102 performs a stroke every time a space is cast, The disk 166 has a projection 167, which is connected with a spring 168 and is arrested after each movement by means of a spring-actuated catch 169 on vthe lever 158. After ten movements the disk 166 with its projection touches the catch 169, as shown in vFig.' 12. At the eleventh movement of the .disk 166 the projection 167 moves the lever 158 by means of the catch 169, and thus lifts the catches 161 ont of the' toothed rims of the disks 5l 53' 58 59. These disks thereupon spring back into their original positions be- 'the beginning of the next line.

fore the eleventh space is cast, so that the eleventh and'following spaces are made of normal thickness. lf at the end of the line the pin 162 is actuated bythe operation of hole 1V, Fig. 13, While lever I101 192 assumes its normal position (illustrated in Fig. 123) and lever 15S is displaced, then a piu 170 lever 158 raises the catch 165 and a stop- 171 withdraws catchl 169 from the ratchetdisklde, so t. the latter also can return to its norinai position under the infinence ofthe spring 166 in ord-er to resume its function at lf the line has only ten or less than ten space-places, the parte.comeV into the positionlillnstrated in Fig. 13 before the projection lb'otthe disk 166 becomes operati vof-1.'. c., bef'ore it reaches the catch 16g-so that in this lcase also the disk 166 is returned to its normal position at the end of the line. l l

.In'concluding there may be referred to a modification of the disk A1105',i Fig.' 7. The present invention in its principle ofthe spacing in general limits the combinations of the places in proportion to their length, andtherefore require spaces diiering in thickness very much from the normal spaces. For

- this purpose the zone-line 5 signifies ten units,

and .the step 115 of the disk 110 projects twice as far from the periphery of said disk, as shown in dotted lines by 115. Therefore when this step passes. the roller 121 the opf erative diskis moved around ten teeth and the spacing altered by ten units.
